Instinct triggers fight or flight when you encounter a bear in the woods.
Instinct MIGHT cause a reflexive audible outburst in reaction to someone being a dick in a computer game.
I'm pretty sure it isn't "instinct" that makes you type out a detailed explanation of someone's incompetence and call them names.
If it is, then you are an evolutionary marvel, considering keyboards have only been around for the more recent parts of human society, and computers and the internet even more recently. Scientists would like to study you sir.
I come to hate the word "troll" more and more since people use it way too freely by now ... same as "Feeding" or "Report" ... Accept answers that players give you. We do not do it out of spite or to annoy you, but to show what in our opinion went wrong.
You may not like it, but that it for what it is: Advice to not being here again.
That aside ...
As I stated earlier, the 7-day-ban is an escalation from the last ban which was 3 days, unless you were somehow picked by a Riot employee that personally saw to your ban and deemed it necessary.
The tribunal does not decide how long a player will be banned. (How could we, as we do not see their history or names (which is good)).
